.DAV file is associated with video file types. This format is used by DVR365 software. DVR365 is security equipment which is used to display the video data from CCTV cameras to the monitor.
This hardware also has recording capabilities and the video files are stored in the format of .DAV. A number of CCTV cameras can be connected with the DVR365 hardware and the recording of full day of each CCTV camera is saved with .DAV extension. The file is encoded with a different encoder to ensure quality of video is not lost while keeping the size of video as small as possible.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .DAV file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .DAV file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .DAV file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
